I wish the eGPU scene was a little more refined and mature. It was almost there with Intel thunderbolt but with the M1 we've got an entirely new thunderbolt implementation that barely supports (pretty sure it still doesn't without something like display link) more than one external display for what I can only imagine is a hardware limitation. It seems like we always almost get there and then something new comes along and everyone chases that instead.

M2 is sure to provide what you want. In the meantime, just keep buying.
